Frame rate in trigger mode
With many sensors, the maximum frame rate is lower in trigger mode than in freerun mode because these sensors
expose and transfer sequentially. Which frame rate is possible in trigger mode therefore depends on the exposure
time. The time required for capturing a frame in trigger mode can be approximated with the following formula:
t Current exposure
capture
Example: At the maximum exposure time, the frame rate is about half as high as in freerun mode; at the minimum
exposure time, the frame rate is about the same.
Freerun synchronization
This mode is currently not supported by DCx Cameras.

2.1.3 Standby

DCx Cameras can be set to a power-saving standby mode. Standby mode switches off the sensor of CMOS
cameras and the timing board of CCD cameras. The camera remains open in the software.
In standby mode, the camera cools down and the number of hot pixels visible when longer exposure times are
used is reduced.
Standby is the default state when the camera is not open in the software. When you open the camera or switch to a
different mode (freerun or trigger mode), the camera wakes up from standby mode.
Note
In standby mode, you can continue to use the camera's digital inputs or outputs.
